> In the "Snape's Worst Memory" scene we have the Marauders calling
each other by their nicknames all the time.  No one knew they were
animagi, these could just be silly nicknames they sung out to each
other in the halls. Names that meant something to them, but not to
anyone else.  Remember, the Trio were to call Sirius "Snuffles" when
they were talking about him.  Just a nickname.  Snape could have,
probably would have, heard them calling each other by these nicknames
at school, then seeing all the names on the map, would instantly put
two and two together and believe HP had gotten the map directly from
the manufacturers as he knew one of the manufacturers was currently
working at the school - Lupin/Moony. 

Carol adds:
I agree completely with DuffyPoo. The Marauders seem to have used the
nicknames openly, arrogantly certain that no one would discover their
secret. As for the map ostensibly containing Dark Magic (which Snape,
of all people, would recognize if it were real without the aid of
Lupin or anyone else), I think that was just a ruse to call in Lupin
and find out what he could about the parchment from one of the makers.

Your "manufacturers" reference backs up that interpretation. So does
Lupin's remark, "I'll take this *back* now, shall I?" Back? When did
he have it that Snape would know about? Only twenty years before, when
he and the other Marauders were using it. Snape must have understood
Lupin's meaning, which he could not protest in front of Harry without
revealing Lupin's connection to James and Sirius. He would also have
recognized that Lupin's claim to the map was better than his and would
have (rightly) assumed that Lupin would not return the confiscated map
to Harry--at least not while he was still teaching at Hogwarts.

Lupin, BTW, had his own reasons for keeping the map from Harry or
anyone else (particularly Snape and Dumbledore). He couldn't let it be
known that "the animagus Black" (to steal Bella's term) knew secret
passageways into Hogwarts and might well be hiding in the Shrieking
Shack. Bad Lupin! Maybe not ESE!, but still putting his own needs
before Dumbledore's--or Harry's.
